Publish Github releases from Travis

This release introduces some config to automatically build deploy a
binaries on the github release page using travis. The build only happens
when a commit is tagged and it uses the stable version of rust.

The main travis sections (install/script/before_deploy) have been
moved out of the .travis.yml to make it easier to read, maintain and
extend the different steps of the CI process.

Since checking for the Rust version in CI is enough to know if clippy
should be used or not, the environment variable `CLIPPY` has also been
removed, which further allowed simplifying the CI process.

Besides the executables, some auxillary files are now also published as
part of a release when they have changed since the last tagged Alacritty
release. This should make it clear for returning users when a new
version of a specific auxillary file is required.

Instead of using the 14.04 image which travis provides by default, an
18.04 docker image is used to build the output binaries for Linux.
This affects both the .deb and the .tar.gz binary.

The advantage of this is that while binaries compiled on 14.04, do not
work on 18.04, it does work the other way around. The generated .tar.gz
binary has been tested on 18.04, Debian, Fedora and Archlinux and all
systems were able to run it without any warnings or errors.
